ADJUSTABLE TABLE.

SPECIFICATION forming part of Letters Patent No. 501,638, dated July 18,1893. Application filed December 16, 1892- Serial No. 455,335. (Nomodel.)

To all whom, it may concern.-

Be it known that we, NEWTON M. ANDERSON and GEORGE S. RIDER, citizens ofthe United States, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements inTables; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will'enableothers skilled inthe art to which it appertains to make and use the same. i

This invention relates to tables having vertically adjustable tops; andthe invention consists in details of construction and combination ofparts which constitute the table frame.

In the drawings, Figure 1 is a side elevation of a table in which theinvention is embodied; and Fig. 2 is a plan view, with the support forthe top sectioned at line 2-2 of Fig. 1; and Fig. 3 is a verticalsectional view of the support on line 33 of Fig. l.

The support for the table top A consists of two relatively movableparts, viz., the standard B, which is secured to the base D, and thepost O,-on the upper end of which the table top is secured, The baseDhas legs (1 d which are adapted to support the other parts. Since, inthe precise construction shown, the table top A is so secured to thepost 0, that it lies almost wholly onone side thereof, two of the legsat d are extended so they bear upon the floor at points under the outeror unsupported portion of said top. In the base is formeda verticalsocket d which is adapted to receive the lower ends of the two sectionsof the standard.

The standard Bis composed of two separable parts I) b. When placed andheld together as shown in the drawings, there is a space between themwhich isadapted to receive the post 0; and their lower ends enter thesocket d in-the base. Each section b b is provided with an external beadb which engages with that part of the base immediately around thesocket. Each section is also provided, at its lower end, with aninwardly turned flange b which engages with the head of the bolt E. Theedges of the flanges lie close together, but curve away from each othernear their middle parts so as to permit the passage of said boltEbetween them. The bolt also passes through a plate F which lies acrossthe lower end of the socket d, and may either be made integral with thebase or separate therefrom as desired. The nut e which screws onto thebolt E, engages against said plate and holds the two sections of thestandard in the said socket. The post 0 lies and is movable in the spacebetween the two sections of the socket; and is of such shape that itwill be clamped between them when the upper parts of the sections 1) bare drawn together. A bolt G passes through both sections 1) b, and bymeans of the nut 9 said sections are drawn toward each other. The post 0is slotted vertically and the bolt G passes through said slot.

In setting up the described frame, the bolt E is placed between the twosections. of the standard, and the lower ends of said sections areinserted in the socket b. The nut e is screwed onto the bolt which isprevented from turning by the engagement of its head with the sides ofsaid sections. The post 0 is then placed between said sections, and thebolt G passed through the holes therein and the slot in'said post; andwhen the nut g is screwed onto the bolt the entire frame is connected,and the means for adjusting the elevation of the table top are provided.

In order to avoid the necessity of nicely fitting the post to the spacebetween the sections b b (which would increase the cost of the frame)the vertical edges of the post 0 are made of V-shape, and the proximateedges of the sections are provided with oppositely beveled surfaces b bThe V-shaped edges lie between said beveled surfaces, and therefore whenthe two sections are drawn together, the post automatically adjustsitself to be firmly grasped between said sections.

Having described our invention, we claim 1. The combination of a basehaving a socket, a standard composed of two separable sections which areseated in said socket, each section having an external bead and aninwardly turned flange, a plate over the lower end of said socket, and abolt passing between said flanges and through said plate, with a postlongitudinally movable between said sections and means for drawing saidsections toward each other thereby clamping said post, substantially asand for the purpose specified.

'2. The combination of a base having a socket, and a standard composedof separable In testimony whereof we affix our signatures sections whichare seated in said socket, and in presence of two witnesses.
